iii)  As one can see already from the power counting arguments,
the renormalization of the the Einstein-Hilbert term in QG based
on GR is possible only owing to the nonzero cosmological
constant \(\Lambda \) . This feature holds beyond the one-loop order and
can be seen as a general result. However, this
statement corresponds to the most universal, logarithmic,
divergences. The quadratic divergences of the Einstein-Hilbert
type are possible even for \(\Lambda =0\) . However, we know that these
divergences depend on the choice of regularization and, therefore,
the physical results which one can obtain from quadratic
divergences always have uncertain physical sense. This issue was
discussed in more detail, e.g., in [1]}.
